what is "normal" urine flow rate?

I'm a male in my early 40s who may be starting to have prblems with prostate enlargement. I went to the doctor and had a urine flow test and the max rate was 25 (I'm not sure what the units were). What is the range of a normal urine flow rate for someone my age?

I would have to say you're still doing pretty good, i saw this on another site:
